APPROVED BY ________________ Lt Col Golam Saklayen Associate professor Dept of Mechanical Engineering Millitary Institute of Science and Technology(MIST) 4 | P a g e Abstract: In our studies we focused on area of sourcing, converting and delivering sustainable energy. Concentrating at the potential role of solar power. Power generation through a solar updraft tower (SUT) has been a promising novel approach for sustainable generation of renewable energy. Developing nations are faced with the challenge of industrialization, population increase and urbanization. These changes have stressed energy supply generated from conventional fossil fuel. Conventional sources are insufficient to meet the increasing demand of a developing, industrious nation (e.g. Bangladesh). A solution to adequately generate sustainable amount of energy from a renewable source is quintessential. This solution will support the rapidly increasing population and economic development. Our project plays important role in reducing electricity crisis and forming an essential part of the solution. The electricity generated can be supplied to the national grid and available to the population. This will mean reduced cost for the government in the long run and also will allow the government to reduce its dependency on costly and unsustainable fossil fuel. This cost reduction benefit can be passed on to the public as reduced energy cost or preferably through nationwide energy infrastructure development.This technology will not only help with the energy concern of Bangladesh but also will help to improve the situations of other developing countries alike Bangladesh. All in all this technology will be able to contribute towards a better world and form a part of an integrated ecosystem of sustainable energy technology 5 | P a g e Contents CHAPTER 01: INTRODUCTION

Received: 26 November 2020; Accepted: 14 December 2020; Published: 16 December 2020 Abstract: To facilitate sustainable energy development, one has to understand the limited availability of nonrenewable energy resources, and the ability of the earth to renew or recover. Emergy is an instrument that measures environmental loading, ecological economics, and regional sustainable development. In this study, emergy indicators are calculated to investigate the sustainability of solar updraft tower (SUT). SUT produces energy from the hot air, utilizing a combination of a solar collector, central tower, and air turbines. The results demonstrate that the sustainability of SUT grew as the size of the plant increased. Further, emergetic ternary diagrams are drawn to facilitate the comparison between SUT and various technologies. The resources-use efficiency of wind energy and SUT, 200 MW is found to be the lowest among all energy technologies presented in this research. Scenario analysis is performed to explore the future optimization directions. The results demonstrate that the development direction of SUT systems should mainly focus on reducing the materials demanded by the manufacturing and construction of its solar collectors. This study aims to demonstrate the value of emergy as a powerful instrument for drawing long-term sustainable strategies in energy markets for a greener tomorrow.

  • Solar Updraft Towers
    Solar Updraft Towers CEE 491 Presentation 5 Travis Satsuma May 5, 2009 Project Description Produce energy by harnessing simple theory of hot air rises Collects hot air and uses it to spin turbines to generate electricity How it Works Design is based on three well- known thermal principles: 1. The use of the sun’s radiation to heat a large body of air (collection area), greenhouse effect lets light in, direct and diffuse, but does not let heat out. Collection area uses material such as single or double polyester material to capture heat 2. Hot air rises (through a chimney) 3. Movement of air as energy source to drive large turbines to generate electricity (basic engine). Two Primary Factors Size of the Collector Area ◦ With a larger collector area, a greater volume of air is warmed to flow up the chimney; collector areas as large as 7 km in diameter have been considered Chimney Height ◦ With a larger chimney height, the pressure difference increases the stack effect; chimneys as tall as 1000 m have been considered Green Energy Unlimited renewable energy source in the sun Works 24/7 ◦ Ground is heated during the day and emits radiation at night to keep turbines running 24/7 CO 2 only produced during construction of tower History In 1903, Catalan Colonel of the spanish army Isidoro Cabanyes first proposed a solar chimney power plant in the magazine La energía eléctrica . One of the earliest descriptions of a solar chimney power plant was written in 1931 by a German author, Hanns Günther . In 1975, Robert E.

  • Solar Chimney from Wikipedia, the Free Encyclopedia
    Solar chimney From Wikipedia, the free encyclopedia This article refers to a device for ventilation. For the power generation technology, see Solar updraft tower. A solar chimney — often referred to as a thermal chimney — is a way of improving the natural ventilation of buildings by using convection of air heated by passive solar energy. A simple description of a solar chimney is that of a vertical shaft utilizing solar energy to enhance the natural stack ventilation through a building. The solar chimney has been in use for centuries, particularly in the Middle east and Near East by the Persians, as well as in Europe by the Romans. Contents 1 Description 2 Solar chimney and sustainable architecture 3 Precedent Study: The Environmental Building 4 Passive down-draft cooltower 5 See also 6 References 7 External links Description In its simplest form, the solar chimney consists of a black-painted chimney. During the day solar energy heats the chimney and the air within it, creating an updraft of air in the chimney. The suction created at the chimney's base can be used to ventilate and cool the building below. [1] In most parts of the world it is easier to harness wind power for such ventilation as with a windcatcher, but on hot windless days a Solar chimney can provide ventilation where otherwise there would be none. There are however a number of solar chimney variations. The basic design elements of a solar chimney are: The solar collector area: This can be located in the top part of the chimney or can include the entire shaft.

  • Solar Updraft Tower - Wikipedia 1 of 14
    Solar updraft tower - Wikipedia 1 of 14 Solar updraft tower The solar updraft tower (SUT) is a design concept for a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a hot air updraft in the tower by the chimney effect. This airflow drives wind turbines, placed in the chimney updraft or around the chimney base, to produce electricity. Schematic presentation of a solar updraft tower As of mid 2018, although several prototype models have been built, no full-scale practical units are in operation. Scaled-up versions of demonstration models are planned to generate significant power. They may also allow development of other applications, such as to agriculture or horticulture, to water extraction or distillation, or to improvement of urban air pollution. Commercial investment may have been discouraged by the high initial cost of building a very large novel structure, the large land area required and by the risk of investment. However, there is renewed interest in solar updraft towers, especially in sunny remote areas. A few prototypes have recently been built, and projects are proposed for parts of Africa, the US and Australia. In 2014, National Geographic published a popular update, including an interview with an informed engineering proponent. A solar updraft tower power plant can generate electricity from the low temperature
